Depends on which rich person you are talking about:
(1) Executives at a large C-Corp: They get paid tradition income tax. Some buck the system, like Buffet, and issue stock options instead. For C-Corps the corporate, payroll and capital gains taxes effects their employment decisions not the income tax.
(2) The Rich Personal Investor: Income tax won't effect this guy since he is just investing his own money. HOWEVER, capital gains will. Say he is a venture capitalist. Capital gains will take away the amount he can invest in business or product he wants to invest in. Its also is disincentive to invest in the first place. Herman Cain is 100% right when he says capital gains are barrier between the business and the investor. Raise CG and you hurt people with big great ideas needing an investor.
(3) The Trust Fund Baby: They have other people manage their money. Not going to help or hurt them no matter where their taxes are at.
(4) SUCCESSFUL Small Business NON-C-Corps: This is 60% of the employers. Small businesses are defined as companies that employee <500 employees. Some small business aren't so small. These business can be SP, Partnerships, LLC, LLP and S-Corps. All these organizations have flow through taxation. So unlike the C-Corps they are not taxed at the entity level (Corporate tax) they are taxed on income by the owners. That mean they get hit with the income tax. Any raising in the income tax takes money away from the business. Take money away from the business mean cuts in other place (usually employment) and less hiring. Raising income tax hurts big time on employment here.
Then you have the payroll tax. While the payroll tax hurts C-Corps its a small business killer!
It also depends what you mean by rich. If you think rich is, as Obama thinks rich is, $250K and above then you are going to hit alot of Successful Small Business employers. If you think rich is $1 mil and above then you are probably save in that fact that it will hit mostly executive and highly compensated key employees in C-Corps, hence no effect on hiring.
If your small business profits more than 250k a year its probably not small.
Sure it is. It can be a one or two employee operation.
Or it can be a 500 employee operations with 20 shareholders in an S-Corp
